Of 33 Staphylococcus spp. isolates, 17 were coagulase-negative staphylococci. Ten isolates were in posttraumatic endophthalmitis group, and 5 and 2 isolates were in postoperative and endogenous endophthalmitis group, respectively. #Other fungi included Bipolaris sorokiniana, Mucor, and Penicillium.
